How can I implement filtering in ASP.NET MVC?

You can implement filtering in ASP.NET MVC by using query parameters in your controller actions to filter data based on user input.

Can you show me an example of how to set up the controller for filtering?

Sure! In your controller, you can create an action method that accepts filter parameters. For example:

public ActionResult Index(string searchTerm)
{
    var items = db.Items.AsQueryable();
    if (!string.IsNullOrEmpty(searchTerm))
    {
        items = items.Where(i => i.Name.Contains(searchTerm));
    }
    return View(items.ToList());
}

What about the view? How do I create a filter form?

In your view, you can create a simple form to capture the filter input. For example:

<form method="get" action="/YourController/Index">
    <input type="text" name="searchTerm" placeholder="Search..." />
    <input type="submit" value="Filter" />
</form>

Is there a way to apply multiple filters at once?

Yes, you can add more parameters to your action method and include additional input fields in your form for each filter.
